# opt in to using the `metadata_csum_seed` feature of the ext4 filesystem
# for the /boot filesystem. Support for this was only recently added to grub
# and isn't available everywhere yet so we'll gate it behind this image.yaml
# knob. It should be easy to know when RHEL/RHCOS supports this by just flipping
# this to `true` and doing a build. It should error when building the disk
# images if grub doesn't support it.
